1. Field of the Invention
This invention relates to power and voice/data communication transmission systems for use at or beyond the demarcation point in a residential or business building.
2. Description of the Prior Art
In some conventional telecommunication devices, such as with answering machines, cordless and cord telephones, there are instances where an undesirable plurality of cables connect each of said telecommunication devices for voice/data transmission and electrical power transmission. As an example, elective telephone service features such as Caller ID™ or Call Display™ offered by telephone companies require two cables to be run to certain telephones using this service. The first of said cables carries the voice/data communication transmission, whereas the second of said cables carries power to operate the elective service in the telephone. One such telephone is the Nortel™ made Maestro™ model telephone. Such telephones feature-capable telephones now conventionally require a power supply cable to connect the telephone to a nearby electrical wall outlet via a DC adaptor. In addition to the power supply cable, there is also the traditional voice/data cable that connects the telephone to the telephone jack. Accordingly, there are two cables and one DC power adapter in the set up for each such feature-capable telephone. A similar conventional cabling layout is required for a stand-alone answering machine or a cordless telephone whether or not any elective feature services are available. There are a number of disadvantages that flow from the current conventional setup.
First, having two cables and a DC power adapter results in an undesirably messy, and cumbersome setup at each such conventionally laid telecommunication device location. Second, children have been found to play and tangle themselves in the array of cables that loosely dangle behind each such telecommunication device. The problem escalates when the notion that many homes or businesses have three or more such devices at different locations in their premises--all requiring the same setup. It is desirable to have a system in which there is a reduction of the number of cables required at each telecommunication device installation.
It is an object of the invention to provide a system in which the layout of the cables required for a telecommunication device such as a feature rich telephone, a cordless telephone (either feature-rich or not) or an answering machine is simple and the limited to one cable per installation that is easily managed.
It is another object of the invention to reduce the number of cables required at a telecommunication device installation.
The invention effectively utilizes the spare unused line that is found in the telephone wiring in a house to distribute power through it. In a first embodiment, the invention comprises an interface (hereinafter referred to as a "power input module") in which a single power source feeds power into the unused line at the demarcation point. As a result, the internal telephone wiring running throughout the house is now powered from a single source and the power may be accessed via regular telephone jacks. All that a user needs to do to get power and voice from a telephone jack is to connect a telecommunication device, such as a telephone, to a new combined power-communication cable. The new combined power-communication line makes use of the dual transmissions, namely voice/data communication and power, accessible from the telephone jack. Advantageously, there is only one cable (separated only at a point near the telephone) necessary at each telephone. Moreover, there is no need to have a power transformer at each telephone connected to a power supply outlet. When all devices require the same voltage, only one central power transformer is required (at the demarcation point interface).
In the invention, there is provided a combined power and communication delivery system for installation at or beyond the demarcation point in a residential or business building, said system comprising: a power input module; a plurality of traditional voice/data communication lines, one of said lines being an unused voice or data communication line and being connected to said power input module thereby making said first of said lines a current-carrying line, said plurality of lines terminating at least one female multi-wire telephone jack; and, at least one power-communication cable, said cable characterized by a first end being a male multi-wire plug to releasably engage said female multi-wire telephone jack, a second end partially depending from said first end carrying one or more voice and data communication transmission lines, and a third end partially depending from said first end to transmit current from said current-carrying line.
In another embodiment of the invention, namely in situations where there are different telephones sharing the same voice/data communication line, but requiring different DC voltages, the present invention may be adapted to include a multi-interface power input module to accommodate power for each DC voltage level. In this case, there would be more than one current-carrying line.
In another embodiment of the invention, the combined power-communication cable may include a fourth end also depending from said first end carrying current from said current-carrying line, or a second current-carrying line.
Further features of the invention will be described or will become apparent in the course of the following detailed description.
In order that the invention may be more clearly understood, a preferred embodiment as well as alternative embodiments thereof will now be described in detail by way of example, with reference to the accompanying drawings, in which:
For the purposes of this description, the "demarcation point" is the location where the wires that are inside a residential or business building are connected to the telephone company's network. Usually, this connection occurs at a "network interface device". The network interface device is usually the small black box where the telephone wires inside a dwelling are connected to the telephone company's network. Typically in older dwellings there may not be a network interface device, but instead a network interface jack or also referred to as a demarcation jack. The demarcation jack is located inside the dwelling to accommodate the connection of the inside wires to the telephone company's network. In a multi-unit or multi-storey building, the demarcation point exists at the location that the telephone company wires connect to the main jack in the apartment unit. In a retail or business unit, the demarcation point is the location that the telephone company's wires enter the unit and are connected to the inside wiring. Any telephone wiring beyond this demarcation point is usually the customer's property and not the telephone company's. The present invention utilizes the unused/dormant telephone wiring at or beyond the demarcation point in the customer's premises as part of a system to deliver both voice/data communication and power to telecommunication device.
It is to be understood that in a typical residential dwelling there is sufficient telephone wiring pre-installed for service of at least two telephone lines therein. In most cases, however, the customer has elected to activate only one line. The second line remains dormant and unused. The idea behind leaving wiring for a dormant line in a building is to limit the costs to the end user should the user choose to have a second line activated by having the second line wiring pre-installed throughout the dwelling. This practice is similarly executed in business buildings as well. In some instances, buildings may have telephone wiring set up for service for four lines or more. In all those instances, there is usually an "extra" line left dormant or unused ready for activation at a later date. The invention described herein utilizes the dormant or unused line to provide a combined power-communication delivery system for communication devices, such as telephones, answering machines, caller identification devices, etc. The invention may also be used when there is no pre-installed dormant line wiring. In that case, the customer must install additional wiring to act as a power transmitting line to make use of the invention.
The invention will be now described in connection with preferred and alternative embodiments, but for the sake of brevity the following description describes the situation where there is one active line and one dormant line; however, it will be understood that the description is not intended to limit the invention to this situation only. As such the description is intended to cover all alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
